The 7I40 is a Dual H bridge driver for two brush type motors or other inductive loads. The 7I40 is available in low voltage and high voltage models (7I40-LV and 7I40-HV). The 7I40-LV is rated at 10A 40 VDC per axis while the 7I40-HV is rated at 7A 80 VDC per axis. Each bridge on the 7I40 has selectable overcurrent limits of .75 times and 1.5 times rated current. An overvoltage clamp protects the 7I40 from inductive voltage surges, reducing the need for large motor supply capacitors. Low on resistance MOSFETs and high performance gate drivers give the 7I40 high efficiency and low dead time to support switching rates up to 100 KHz. Gate power is derived from logic side power so that unlike other bridges, the drivers are functional all the way down to 0V motor power supply, allowing safe and easy initial setup and testing. The 7I40 also includes encoder input conditioning. Encoder inputs can be either single ended or differential. The 7I40 is compatible with the MESA's 4I27 or the 4I34M, 4I65, 4I68, 5I20, 5I22 and 7I60 Anything I/O cards with SoftDMC or HostMot firmware, or can be used with a customer supplied controller.
